.setAutoThreadsEnabled(enabled) -> Enable or disable automatically adjusting the number of threads for optimal performance. This feature is experimental.

.getThrottle( ) -> Returns the current throttle value.

.setThrottle(throttle) -> Set the fraction of time that threads should be idle. A value of 0 means no throttling (i.e. full speed), a value of 0.5 means that threads will stay idle 50% of the time, with 0.8 they will stay idle 80% of the time.
